COAL-SAVING COMPOSITION.

Io Drawing.

- for the purpose of economizing in the latter, and it consists in the product hereinafter described and claimed.

An object of my invention is to provide a composition which when burned with coal, i. e., bituminous coal, will coke the latter, the result being that the volatile gases which are first driven off are consumed, and the coke is subsequently consumed, thus utiliz' ing substantially all of the heat giving properties of the coal.

A further object of my invention is to provide a composition which when spread on the top of soft coal, after the latter has thoroughly ignited, prevents the escape of gases which might be used in generating heat, but which without the composition would pass up the chimney in the form of smoke.

A further object of my invention is to provide a composition which is in the nature of a plastic mass, the use of which in the manner hereinafter described will cause a fire of soft coal or the like to last much longer than a fire which has not been so treated.

A further object of my invention is to provide a composition of matter which is designed to be used with soft coal so as to render the care of a fire less arduous, since it does not require the'attention which an ordinary soft coal fire requires because of the fact that it burns slowly and steadily.

Other objects and advantages will appear in the following specification and the novel features of the invention will be more particularly pointed out in the appended claims.

In carrying out my invention, I provide a composition having the following ingredients in the proportions stated:

Sand (common or white) 12 lbs. Fine coal (coal dust or slack) 3 lbs. Ashes (any kind) or sawdust 3 lbs. Salt (sodium chloride)... e 2 lbs.

Application filed January.%), 1922. Serial No. 528,082.

Water, enough to make'the mixture like mortar.

The sand, coal dust, ashes, and salt are first thoroughly mixed dry and may be kept in a dry state until ready for use. Enough water is mixed with the dry material to form a plastic or mortar-like mass. When the coal fire is burning well, it is spread on top of the fire with a'shovel in a layer from one-half to two inches thick, and is preferably smoothed down with the back of the shovel.

The composition rapidly dries out but forms a blanket which causes the coking of the coal. It will be noted that the composition contains fuel which is burned so that when it is desired to replenish the fire more coal can be put directly on and the ashes shaken down so that the fire will have a good draft. The composition breaks up into a powder and may be removed with the ashes. This is facilitated by the provision of the coal dust in the composition since without it, the composition would tend to cake.

The composition can be used in a stove, in a grate, or a furnace. It can be used on the top of a wood fire, but must be applied in a thinner coat than for a soft coal fire.

It will be noted that this com osition is not of the class of those so-calle fuel savers which contain fuel in a concentrated form or oxygen supplying materials. It is a composition which is designed more to regulate the burning of the fuel. I have tried the composition and have found it to admirably perform the functions above mentioned.

I claim:

1. A fuel saving composition consisting of a mixture of sand, fine coal, ashes, salt, and water sufficient to make mortar-like mass.

2. A fuel saving composition consisting of a mixture of the following ingredients, in the proportions stated, sand12 lbs., fine coal3 lbs., ashes3 lbs., salt-2 lbs, and water sufficient to make a mortar-like mass.
